Abstract: Objective To review the scientific research advances in the field of preschool children's nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. Methods High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. Results A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". Conclusions The number of English literature published in the field of preschool children's nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children's nutrition in China may need to focus on the external determinants of preschool children's nutrition, such as parental education, diet and food supply.

摘要： 目的 对2012—2022年学龄前儿童营养领域的科研成果进行梳理,旨在为该领域相关政策制定和科研探索方向提供参考依据。方法 通过 Web of Science(WOS)和中国知网(CNKI)数据库检索筛选出 2012—2022 年国内外在学龄前儿童营养领域发表的高质量文献作为数据来源,使用 Excel 和 CiteSpace 软件对其研究热点和前沿趋势进行可视化分析。结果 共纳入英文文献 1 816 篇,中文文献 110 篇。研究机构和研究作者合作网络密度均较低。排除检索词,英文文献关键词中心性前三的是“vitamin A”(0.74)、“intervention”(0.67)、“obesity prevention”(0.55);中文关键词中心性前三的是“贫血”(0.41)、“肥胖”(0.38)、“营养状况”(0.18);中英文聚类排名第一的分别是“贫血”和“physical activity”;最新的突现词是“膳食模式”和“diet quality”。结论 在学龄前儿童营养领域的英文文献发文量呈上升趋势,国内近3年呈下降趋势。我国在该领域研究较少,研究热点多集中在学龄前儿童营养现状研究方面,对干预性研究、方法学探索的关注度较低,未来我国在学龄前儿童营养领域研究热点可能集中在学龄前儿童营养外在决定因素,如父母教育、饮食方式、食物供给方式等。
